Abstract (en)
[origin: EP3253136A2] The present invention relates to a wireless communication system. Specifically, the present invention relates to a method for controlling transmit power and an apparatus therefor, the method comprising: a step of configuring a first cell group consisting of a PCell and zero or more SCells, and a second cell group consisting of one or more SCells; a step of determining transmit power of a first PUCCH to be transmitted through the PCell in a subframe #n; and a step of determining transmit power of a second PUCCH to be transmitted through a predetermined SCell in the second cell group in the subframe #n, wherein the transmit power of the first PUCCH and the transmit power of the second PUCCH are adjusted so that the total sum of transmit power of a terminal is not greater than the maximum transmit power of the terminal, considering a minimum guaranteed power which is assigned to each cell group according to protection priorities between cell groups, and the minimum guaranteed power which is assigned to each cell group is selectively applied to a specific UCI among a plurality of UCIs.
